The purpose of this study was to examine whether a simulation-integrated context-based 7E instructional strategy (SICBIS) could increase students' achievement in the chemistry of oxides, acids, bases, and salts (COABS) when compared to context-based 7E instructional strategy (CBIS), simulation-integrated conventional teaching approach (SICTA), and…

We show how learning can be improved, beyond that shown in actively taught classrooms, by also transforming the homework using the principles of deliberate practice. We measure the impact of transforming the homework on student learning in a course that had already implemented an active approach to teaching in class. We compare performance on the…

We present the development and validation of a construct map addressing introductory quantum mechanics topics at the high school level, as a subset of a larger learning progression on quantum mechanics. Topics include energy quantization, photon absorption and emission, the Heisenberg uncertainty principle, atom stability, orbitals, wave function,…

Purpose: This study aimed to investigate the potential effects of problem-based learning (PBL), predict observe explain (POE), and PBLPOE on students' problem-solving skills and self-efficacy in Biology. This research is based on various facts that problem-solving skills and self-efficacy of Indonesian students in biology subjects are still low.…

The COVID-19 outbreak has altered chemistry laboratory instruction and forced us to reconsider the balance between face-to-face and online teaching. Our students preferred face-to-face teaching (score 4.1/5 on a Likert-like scale) to virtual laboratory exercises (3.4/5) despite the fact that their performance score was actually lower in…

Most of the available information on studying under the challenging conditions brought about by the COVID-19 pandemic emphasizes a variety of aspects on how to digitalize the whole teaching process. Thus, several useful and potentially game-changing strategies have been reported recently. In contrast to the digitalization of teaching, in this…

Two science teaching workshops for students of the elementary teacher education degree course at the University of Palermo, Italy are discussed, one based on inquiry-based methods and the other on "traditional" teaching methods. A questionnaire aimed to understand the teaching styles preferred by students, their reasons for…

Although the implementation of blended learning in organic chemistry is rapidly growing, thus far, there are few studies published on the evaluation of supplemental types of blend in organic chemistry. This report covers a phenomenographic study that was designed to evaluate a supplemental type of blended learning approach implemented in a…

The Flipped Classroom (FC) is a teaching approach in which students gain the first-exposure learning with online materials outside the classroom, and then, in the classroom, they focus on interactive or engaging exercises. Despite its considerable publicity, the studies focused on the FC in primary education are deficient. The aim of this research…

One of the topics students have understanding difficulties in science is pressure. The study investigates the effectiveness of an active-learning environment on the students' understanding of the concept of pressure. The sample consisted of 30 students from a public secondary school in Turkey. This study used a pre-test, post-test,…

Laboratory experimentation in the context of school science is a widely advocated teaching strategy for the simplification of several abstract scientific concepts. Laboratory-based learning activities have proven to enhance learners' conceptual and procedural understandings of micro chemical phenomena, thus boosting achievement in chemistry…

Project-Based Learning has been the leading strategy used by most of the top educational systems in the world. Authentic learning that addresses the 21st century skills is what PBL offers. However, little research has been done to explore its potential in improving the quality of education in the country and what framework to be used to be able to…

Web-based learning is a growing field in education, yet empirical research into the design of high quality Web-based university science instruction is scarce. A one-week asynchronous online module on the Bohr Model of the atom was developed and implemented guided by the knowledge integration framework. The unit design aligned with three identified…

The purpose of this study was to explore the effect of problem-based learning (PBL) on student achievement and students' perceptions of classroom quality. A group of students taught using PBL and a comparison group of students taught using traditional instruction were studied. A total of 457 students participated in the study. Pre- and…

Promoting collaboration and discourse in asynchronous online courses is challenging; students need something engaging to talk about, a communications medium in which to fluidly discuss it, and a social environment that supports discourse. We designed a fully online introductory geoscience lecture and lab course called Geology Goes Hollywood that…
